The problem I find with Community is the inconsistency with some of it's characters. Britta, for example, has been turned into a complete wacko compared to her role in the first season. I'm not sure why Shirley is even among them. The group vastly ignores Pierce (and his shenanigans), when he does a much better job than Shirley. Troy & Abed have a great bond and co-ordination, however, they have thrown that out of the window, in the current season, by pairing Britta with Troy. It's a ridiculous decision. Annie shows real promise in the episodes which requires her to be in a character role.
The only consistent characters I find on the show are Abed, Jeff and the Dean. They stick to their characters and portray them flawlessly. Danny Pudi, especially, is a genius. He always manages to deliver when it comes to solid comic performance, knowingly or unknowingly.
This is why I loved the first season. It was fresh, it had characters you would really connect with and the humour was spot on. But there is a vast difference between then and now. You would either love, or absolutely loathe some of the episodes. The last good and probably the best episode on the show was 'Digital Estate Planning' from season 3. I couldn't watch the last 2 episodes of season 3 and decided to move onto season 4. It was after watching the first 3 episodes did I decide to call it quits. I'm sorry, but the show's quality has taken a complete nose dive. For those who still continue to like it, good for you. But to me, this show is dead.
